Application filed July 6, 1908. Serial No. 141,991.

To all whom it may concern: H

Be it known that we, CHARLES E. KRUE- GER and WILLIAM H. KRUEGER,citizens of the United States, residing at Minneapolis, in the county ofHennepin and State of Minnesota, have invented certain new and usefulImprovements in Combination Gages and Bevel-Squares and we do herebydeclare the following to be a full, clear, and eXact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention has for its object to provide an improved tool in thenature of a combination gage and bevel square, and to this end itconsists of the novel devices and combinabars.

tions of devices hereinafter described an defined in the claims. 1

In the accompanying drawings which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a plan view of the im ro'veddevice. Fig. 2 is a side elevation of t e same; and Fig. 3 is a viewcorresponding to Fig. 1, but with some parts broken away and with theparts shown in different adjustment than that illustrated in Fig. 1. r

A bifurcated gage plate 1 having parallel graduated arms or s1deportions 2 is provided with an intermediately located graduated segment3. Said gage plate 1, at the aXis of its segment 3, is pivotallyconnected,-

by a screw t having a knurled nut 5, to an underlying segmental flangeof an angular plate 6, to the depending flange of which a head block 7is shown as secured by means of a nutted bolt 8. The angular bracket 6is provided with a pointer 9 which is bent upward and over the graduatedsegment 3 and cooperates with the latter to indicate in degrees theangular position of the gage plate in respect to the head block 7.Longitudinally grooved guide bars 10 overlie the graduated sides of thegage plate 1 and are rigidly secured thereto at their ends by rivets orbolts, but are spaced slightly apart by thin spacing blocks 11.Extending transversely of the graduated arms 2 ofthe gage plate 1 is agraduated scale or bar 12, the ends of which are arranged to slidebetweenthe graduated arms 2 and the overlying slotted guide bars 10, andare adjustably connected to the said guide bars by clamping screws andnuts 13, which screws work in the slots of the said In connection withthe device described,

there is provided a sort of a T-square,, both the blade 14 and headportion 15 of which are graduated. The head'portion 15 of this T-squareis long and its ends work between the graduated arms 2 and the slottedguide bars 10 and clamping screws. and nuts 16, which nuts work throughthe transversely intersecting slots of said bars 10 and head 15-, serveto secure the said T -square in any desired adjustment. The blade 14 ofthis 1'.- square is made up of a pair of thin metal strips 12 slightly saced apart so that they embrace the scale ar 12.

The gage plate 1, with the parts carried thereby, is adapted to beturned into any angular position in respect to the head block 7, so thatthe device may then be used as a bevel square or for various otherpurposes requiring work to be laid out at an angle. Both the if-square1415 and the scale bar 12-may be set in various adjustments on the gageplate, as is made evident by comparing Figs. 1 and 3. The said artsmaybe set for marking an angular ho e of any dimensions, within certainlimits of course, and the tool may be set for locating the said hole atany desired angle in respect to the same straight edge or surface.

The device will be found very convenient for marking out lock seats indoors, for marking out mortise and miter joints and various notches andseats for various purposes. It is also capable oibeing used as a markingcompass or caliper in measuring thickness of bodies.

I/Vhat we claim is:

1. In a tool of the kind described, the combination .with a gage platehaving laterally spaced graduatedarms, of a scale extending transverselyof and adjustably secured in respect to the graduated arms of said gageplate, and a graduated sf-square adjustab y secured in respect to thearms of said gage plate and to said scale, substantially as de scribed.

2. In a tool of the kind described, the combination with a gage platehaving laterally spaced-graduated arms and slotted guide bars secured tobut spaced apart fromthe arms thereof, of a scale having its endsinterposed between said graduated arms and slotted guide bars andadjustably' secured to the latter by clamping screws and nuts, and agraduated T-square having a slotted head arranged to work between thearms of v said gage plate and said slotted guide bars and adjustablysecured to the latter by clamping screws and nuts Working in the slotsof said guide bars and head, said T- square having a blade made u oflaterallv spaced members between which the said scaleis passed.

3. In a tool of the kind described, the com-v bination with a headblock, ofa gage plate pivotally connected thereto and provided withlaterally spaced arallel arms, a scale bar adjustably secure at its endsin respect to the arms of said gage plate, and aT-square adjustablysecured in respect to the arms of said ga e plate with its bladeoverlapping said sca e bar.

4. The combination with a head block, of a gage plate interlnediatelypivoted to said head block and provided with a graduated segment andwith laterall spaced-graduated arms, said head block avmg a pointercooperating with said segment, a scale bar adjustably secured at itsends in respect to the graduated arms of said gage plate, and a agraduated T-square connected 'to the graduated sides of said gage platewith freedom for transverse and longitudinal adjust- I ments, and theblade of whichT-square overlaps said graduated scale, substantially asdescribed. I

In testimony whereof we aflix our signatures in presence of twowitnesses.
